To all 'wl'wm'it may concern:

Bc it known that we. Riou-uen DoLmNonn and Gofrfrnna Bisonorr, bothsubjects of the vGerman Emperor, and both residing at Pforzheim, Baden,German Empire. have invented certain new and 4useful improveients inMachines for lllanufacturing Metal .Ring Fabrics, of which the followingis a specilication.

The pncsent invention relates to a'niachine for manufacturing n'ietalringabrics.

,Accor-dine 4to athis invention a strip of fabric consistingl of a fewrows of metal rings is suitably stretched or held in such niannentha-tthe last longitudinal row -of ,rings is readily accessible. To this rowfun ther links consising,r of open rings are brfiught up, each one insuccession boing hooked through the space or opening presented bytwo ofthe overlapping closed rings, whereupon the open ring is turned througha. certain angle and shut upon the said closed rings.

The fabric is built up in thejollowing planner :--F rom a wire spiralthe first turn seized by a pair of pincel-s and]l after being cut oit'by asuitable tool, is turned on its center and moved toward the strip offinished fabric in such manner that the joint or place of cut of thesevered turn'arrives in the plane of the fabric. In this position thelink will take over the opening,r between the two lov'erlapping closedrings of. the fabric from below and above aty the place where it is tobe hooked through, the said opening first having been enlarged by meanset a widening` tool. Hereupon the open ring, still held by the pincers,is turned once again on its center, in such manner that its one endprotrudcs through the .previously enlarged opening, whereupon it is bentflat, that is closed, by a specially constructed pail` of pliers. i i ,t

The operation of the machine is entirely automatic.

ln order t malte 'the invention more readily unders'ood 1t will now befully described with reference to the accompanying Aet Fig. -1 across-section on line EMF of Fig. 2. Figs. 5-16 show, on an enlargedscale, the different positions of a ring member and the mechanismsnecessary for handling it from the initial seizing to the final closingI position. Figs. 1T, 18 and 19 show the transverse slide with itspincers and accessories in dierentoperating positions. Fig. 2O shows aplan of `part of the upper structure with the mechanisms for actuatingthe saw for cutting-off the rings7 the closing pliers land the Widener.Figs. 21-24: show side elevations ofgrooved and eccentric disks fastonthe main driving shaft. 'Figa 25 shows the means for rotating thespindle for forming the Wire spiral.

The main shaft 1 rotates in the direction of the arrow 2 (Fig. 2) andcauses by means of its end crank 3 (Figs. 1, 2 and 25) crank rod 11 andtoothed segment 5 a rocking motion of the toothed wheel 6. This latteris mounted on and connected. with aspindle 8, provided 'with a removablemandrel 7 by means of a ratchet device, acting in one di rection onlyand covered-in. In this manner, while the shaft 1 makes a halfrevolution, the spindle 8 with its mandrel executes a completerevolution and then remains at rest during,- the second half rotation ofthe shaft 1. Owing to the revolution of the f spindle the wiretl (Figs.1, 2 iand 6) for the formation of the rings, unreeling from a supplyroller, is helicallyv coilcdupon the mandrel, turn by turn. The pitch ofthe Wire spiral 10 cairhc regulated, as desired,

11. In the drawings, for the, sake of clearness, a wire spiral isshownwith exaggerated pitch. The guide arms 11 are secured to aholder 15,slidably mounted on of the shaft- 14 which is driven oit' the main shaft1 worm gearing 13. By means of vthe eccentric 12, whose ecccntricity isad- "justable by means of the screws 12', the holder 15 with its guidearms 11 and thus the Wire spiral are intermittently advanced so that thefirst wire turn comes opposite a pair of pinceis 17, which' latter turnon the axis 16 (slwuin'iudotted lines in Figs. 1, 2, 17, 18, 19).Hereupon a grooveddisk 18 on the shaft 14 `comes into operation and byoscillating a double-armed lever 19 actuates a slide 2O in such mannerthat the `latter with its upstanding ledge 20 (Figs 2, 3,

by means of relatively adjustable guide arms the spindle `and actuatedby an eccentric 12 17) bends the wire spiral toward the pincers so thatthe first turn arrives within the domain of the jaws of the pincers 17(Figs. and 17). The pincers are mounted on a transverse slide 21 'bymeans of the holder 223, turningI aboutthe axis'lti, and are held in the-horizontal position (Figs. 1, Q, 1'7, 1S) by means of a spring (Fig.l), unless acted'upon by superior lorces. This transverse slide admitsof a fourfold movement, toward"`either side, for *ard and backward.

'1`he"pincers 17 are formed by two jaws, mounted in a holder 23, one jawbeing rigid (the lett one in Figs. 2, 17, 18, 19) and the otherslidable. The latter is inlueneed by a spring 2-1 which has the tendencyto close the pincers, and by pin 25 secured on the slidable jaw andprojecting downwardlythrough a -slot in the holder 23, which contactswith a stop 2G for the purpose of opening the pinccrs upon the latterbeing shifted from right to left. For the purpose oit' clos ing thepincers they areshifted from left to right by a double-aimed lever 2Swhich is turned by a grooved disk 27 on the main shaft 1, and whichengages the slide 2l'. In this manner the pin 25 is released and themovable jaw pressed against the stationary jaw, whereby the tirst turnof the wire spiral is lirmly gripped. During this seizure a circular saw31, mounted on a slide 2t) (Figs. 1, 3,20) and driven by a groovedpulley 30, is let down by the rotary motion ot' an eccentric 32 on themain shaft with the aid of the double-arined lever 33 pivoted at 33',and cuts ott the first turn from the wire spiral. Naturally this cuttingoperation might be equally .well performed by means of a knife, nippersor other tools. The severed link, held by the pincers 17 (Figs. 7 andS), owing to the cooperation of the grooved disk 27 with the lever 2Sand of the grooved disk 35 with the rod 3G v which engages the slide 21,is now by the latter first moved from the left to the right and thenforward. By thelateraln'iovcment, which is merely for the purpose ofavoiding other parts, the pincer holder Q3 with its nose 87 comes withinthe domain oi a slidable cati-11.39 actuated by the gi-'ooved` disk 23S.On thel advance of the holder 23 :trom the posit-ion shown in Fig. 1S tothat shown in Fig. 19, its nose 37 strikes the meeting catch 39 withthev result that the holder is turned upward about the axis 16. Theangle of rotation is 90 degrees, the link 3l, whose center lies in theimaginary efrtensioii of the axis 1G, partaking of tl is rotation. 'lhccut or joint of the link 34.

p will thus be brought from the upper position into the lateralhorizontal position. ln this latter position thefliuk, which is stillspirally directed and is open in trout. can now be so moved'oiwvard.toward the already' finished fabric 1.1, held by a pair ofbroad pliers 10, that the link ends take over this ,fabric from belowand above between t-Wo 'partly contracted or over-lapping rings.

- back into its original4 position, with the joint upwardly, and in sodoing will turn through the two overlapping rings, hooking into,

them, so to say. The turning back of the pint-ers from the vertical intothe horiaontal position is caused by the sliding catch 29 releasing the'nose 37 of. the holder Q3, so that now. the. spring .22 can lay-overthe holder. The next step is the closing of 'the hooked-in, but stillopen link Se by a pair oli' pinccrs #t2 (Figs. 13 and 14). The latterare constructed with a vertically displaceable jaw L' I) (Figs. 1Q, 11and 1.3) and a jaw Ail which slides with the other and is pir'- otcdatl-t. rl`he 4vertical displacement of the..pinccrs l2 is etected bymeans of an eccentric 17 ou the main driving shaft, which acts on thelever V16, pivoted at 40, Vwhich in turn act-uates the slide (Figs. 20and 21). l

On descent from the position ot Fig. 3 the pincers 42 are openand theponion shown in Figs. 14, 1S and l2 is that in which the ring 34 isseized by the jaws of the closing pincers. By closingl these pincers bymeans ol the rod 4) with follower 50 (Figs. 3, 1-1- and 20), actuated bythe eccentric #l5 cl' shaft, 11 and operating the leg oi the rotatablepincer jaw '-l, the link 3l. is closed ilat, that is it 1s bent togetheror iiattened to l'orin a closed ring 51 (Figs. 15 and 1(3).

4The now inished ring` is released by the pincers l2 and 17, whichreturn to their ini; tial position owing to the action of the groovcddisks 17, 2T and 35V. Simultaneously the fabric. held in the pliers l0.must Le advanced the width of a row ot' rings in order that the nextlink to be brought. up by the pincers 17 may in the course ot op.-eration be passed through the next opening between the overlappingrings. as above described. This feed ot' the fabric is ctliected byshitting the slide 523, which carries a pin drum 52 (Figs. i2 and t3)and the pliers 10, in the direction of the drum axis. For this purposethe toothed wheel 55 on a shaft. 5G engages with the rack 51 of theslide 53 (Fig. 3), which shaft 5(3,carries at its end two ratchetdevicesv 5S'. 59 which can be councctcd with it alternately by .means ofa reversing device. l`hc ratchet devices 5S. {if} consist cach ot aratchet wheel and a corre- Asponrling pawl. These ratchet wheels and thcarms carryingY the pa Ils and actuated by the eccentric rods GO. G1 rideloosely on the Vshaft 5G. but are prevented y-from slidinglongitudinally thereof. its shown in Fig.

1, the clicks and 5 9 engage the ratchet i ingly, the shaft 56 Will beintermittently ro 5 The ecc-entries 62, 63 `for the rods 60, 61

are adjustable as to their eccentricity on the shaft 14;. The ratchetWheels are sopitched that the. one, `during the step feed, turns inthedirection of the clock hands and the 58, 59 preventing a turning backof these Wheels during the back throw of the ratchet pawls. On 'theshaft 56 between the ratchet wheels there is slidingly arranged theclutch mernber 57 (Figs. 2 and 3) which can be alternately coupled Withthe correspondingly recessedhubs of the ratchet wheels by means of thedonble-arined lever 67 which swings about the pin 66 and is pivotallyconnectedy tothe clutch part 57. Accord tated in the, one or` the otherdirection, depending upon with which ratchet device the clutch iscoupled at the time. The fabric slide 53, into Whose rack 54 thedriver55 of the shaft 56 cogs, is then correspondingly advanced injthe one orthe other direction,

and each Aadvance movement corresponds to thelwidth of a row ofrings ofthe fabric. Upon oni row being finished the clutch 57 must be shifted sothat the fabric is then dinthe. opposite direction; This reversal offeed iscaused by thev inclined planes 64,

of the slide 53 at the end of its travel'in" 'either direction,alternately coperating with the free ends of the rods 68, 69 which with40 cured to the clutch part 57. Every time the direction of feed of thefabric is reversed, .it must be drawn into the pliers 40 through thespaceofone row of rings, in order that the links for` formation of thenew row may be hooked in, and this is effected by inter mitteiltrotation of the pin drum 52 in clockwise direction. L

For readily drawing-in the finished fabric intothe pliers 40 and yetholding Ait securely during the Work operations, the up-A per one of thetwo plier jaws, pivoted at 40', is yieldin'gly pressed upon the fabricresting on the lower, rigid jaw by a spring or the iikenot shown..

For thepurpose of rotating thepi'n. drum `there is pro'yided a ratchetWheel 7l (lriig. 2), ixed oiithe drum shaft 70, andwith which thereengages the pawl 72 of a lever 74 journaled With its ball-shaped'lowerend in a socket bearing 73. The lever 74 ordinarily is held in theposition shown in Figs. 2 and ai. by any suitable means, for instance a.spring, but owing to its ball and socket as toward the pin deem, and itlies 'Within other in the opposite direction, the clicks bearing it canbe tilted over laterally as Well the domain of the pin. 75 of a disk 76secured toa ratchet Wheel 77 which is loosely mounteden the drum shaft70. This ratchet Wheel 7 7, at each rotation of the main driving shaft,is advanced the distance of one tooth.

by an arm 79 furnished With a pawl 7 8, to

which arm is linked the rod 8O of an eccen tric 8l on the main shaft(Fig. 4). Since the pin 75 -partakesof the rotation of the ratchet Wheel77, it Will, at a predetermined period, coinciding with the reversal ofthe feed of the slide 53, strike `against the lever 71k and takeitalong. By` this tilting movement, however, thel ratchet Wheel 71 onv thedrum shaft 70 will be also advanced through .a certain angle by ineansof the pawl 72 Whichis pivoted to the lever 74 (Fig. 2). The `drum 52likewise partakes of this movement and draws back the fabric through theduring the feed operation, wherebythe lever is shifted toward the pindrum and out of i thedomain of pin The rotation of the ratchet Wheel 7lthus takes place during the feed motion of the pin 75, commencing withthe latter striking the lever 7 fl and terminating with this latterlever ascending the ineline 82. .Upon the lever 74 being freed 'again itreturns into its initial position/ (F i s. 2 and 4 anduvith it the pawl72.

The number of teeth on the ratchet Wheel`71 is such that the finishedfabric at each feed inotionis drawn into the pliers 40 the Width of arow of rings. The number of teeth on the ratchet Wheel 77 mustcorrespond to the numberof individual rings in each row, if

the operation is to be entirely automatic. If the number of such ringsis altered the ratchet Wheel 77 must also be exchanged for another, orthe pin 75 must be set back or ahead in the disk 7 6, after the pin drumhas been fed forward the required distance. The

holes in the disk for adjustably inserting the pin 75 are circularlyarranged, asshown in Fig. 4.

Before the individual rings are hooked-in by the pincers 17 a Widener 83(Figs. 3 and 5) is caused to ascend or descend into kthe fabric in suchmanner that the place at which the still open link is vto be hooked.through, that is to say the space between two :..overlapping rings, isenlarged. The .up and down movement of the Widener `83 is producedbymeans of lever 85, actuated by an eccentric 84 (Figs. 20 and 24) androtatable about the horizontal axis 85 (Figs. l and 20).

The operation of the machine is as follower-After the Wire 9 has beencoiled `about lthe mandrel 7 by the operation of the devices 3, 4, 5, G,and 8 driven from the main shaft 1, the guide arms 11, which take aroundthe thus formed vWire spiral 10, are shifted by the eccentric .12 ofshaft. 14,

ywhereby the first turn of the spiral advances opposite the open pincers1 7 (Figspi and v 17). Hereupon, by the return of 'the slide 20,

which is caused by the operation -of the double-armed lever 19 actuatedby the grooved disk 18, the turn of the spiral is brought between thejaws of the pincers`17 and the latter' closed. This closing Inovementoccurson the pincers moving from the' left end position (Figs. 6, 17)-intothe' intermediate position (Figs. 2, 8),-and is produced by thedouble-armed-lever 28 which causes a lateral displacement of .thetransverse pincer slide 21. This movement is responsible for thesimultaneous shifting of the exterior of the pincers, while the otherjaw, under the influence of the spring 24, with its pin 25 rests againstthe Astop 26,-

until the intended closure'of the pincers has taken place, when theturn' of the spiral is clamped. The circular saw 31'is simultaneously.let down by the lever 33, pivoted at 33", and severs the first turn'34of the Wire.

spiral. .The severed link held by the pincers 17 is now advanced towardthe ring fabric" 41 held in the pliers 40, moving first from:

the left to the right, thatv is from Vthe position of Fig. 2 intothat-of Fig. 18, and then forward toward the fabric. For effecting. thiscomposite movement the pincers are first shifted by the oscillatinglever28 to` Ward the right, and next by the eccentric rod 36 toward thefront (Fig. 19). During this lattermovement the pincers are rotatedabout the prolongat-ionr of the 'axis 16 through the center of the link34C from 'the horizontal (Figs. 7, 18) to the Vertical posi tion (Fig.10, 19), whereby the joint of 'the link is broulht into horizontal'position, and thus intb vthe plane of the fabric. Prior to the arrivalofthe pincers in the front position (Fig. 19H) the Widener 83 has tobring into the proper position 'and to `enlarge the opening betweenthose fabric rings through which the new link is to b e passed.

, When the link,A has been carried over the- .enlarged bythe Widener83,' in such manner that the joint again comes uppermost (Fig.

11). The next step comprises the closing of the still open link toconstitute ,a closed ring. This is effected by means of the ,pincers 42,

i -which for this purpose are moved downward A:es

and their jaws 43, 44 then closed upon the link (Fig. 15). The nowclosed, flat link,

ydesignated by 51 in Fig. 15, is -now finished,

and the described operations are repeated for the next ring formation.The pincers 42, 17 now release the ring and return to vtheir initialposition, while the slide 53 with the fabric carrying drum -52 isshifted through'one division by one of the eccentries 62, 63, dependingupon the `rprevailing direction pffeed. The shifting of the slide 53 iscaused by the eccentric rods 60., 61

(Figs. 1, 2, 3) advancing the shaft 5G step by Astep through the widthof a ratchet tooth by the aid of the ratchet devices 58, 59, one ofwhich is always in engagementwith 'the shaft 56 by meansrof the clutchcoupling 57. The driver 55 of .shaft 56 meshingwith the rack 54 on thesl-ide'53, the 'latter is laterallyv i shifted. v

)Vhen the row of rings (which in .thel

drawings is only partly'l finished) is complete Ithe fabric is drawnback through one division into the pliers 40 by rotation ofthe pin drum,which' movement is produced by"-v nhe parte 80,79, 78, 77, 7 6, 75,82,74g, 72,71." The' eccentric rod 80, upon rotation'of' their.,

main' shaft 1,- hasf caused such *a steppingahead of-v the ratchet Wheel77h :means the pawl 78 that theadjustable-pmn the disk 76, by contactingwiththe lever 74'-,Y 'causes the latters pawl 7 2 -togrotate .the
